How to Fix an Electric Water Heater When Not Having Enough Water?

You would like to take a hot bath and turn on the hot water, but pretty soon does the hot water become cold? There are two things which may cause this problem: Defective lower heating element or defective thermostats. Defective lower heating element can be diagnosed in the following manner. Before we proceed, locate a specification sticker on cover of the water heater. This sticker will tell you the model number, the serial number, the operating voltage and the wattage of the heating element. Turn off the electric power for the water heater.

You will see two units: thermostat and heating element. Disconnect a wire of the heating element by unscrewing the screw.

After disconnecting one wire, you need to measure the resistance of the heating element. At this point, you need a multimeter. 

Read the resistance. We need some physics here. Since the power (in watt) =(voltage*voltage / resistance), the nominal resistance = (voltage*voltage / power). For example, if the operating voltage is 240 V and the wattage is 4500 W, then the nominal resistance is 240*240/4500=12.8 ohm.

If your reading is far from this number such as zero, or the meter doesn't give you any reading, then it is time for you to replace the heating element. If the reading is close to the nominal voltage, then something else is causing a problem.

1. You need to get a new heating element.

2. Before replacing the element, read the instruction on the back cover of the new element.

Don't forget to drain the water in the heater.

Unscrewing the old element may not be easy. If you use a socket wrench, you may need a long hollow bar so that you can have a longer lever arm.

Before installing the new element, I would read the resistance of the new element to see if the new one is not defective. 6. Install the new element by screwing in. After installing, turn on the water valve which goes to the water heater. 7. If there is no leak, then fill the tank. Note that the description above is about the electric residential water heater.

Choosing the Best Water Heaters is a Challenge

This family concern privately owned was started in the year 1919 with the view to enter into the water heater business and even today the company is still owned by the family. The company concentrates on water heating products like consumer and residential boilers, water-heaters, pool and spa heating equipment and indirect water heating systems like tanks for both domestic water and hydronic system tank. From extremely humble initial stages the company has developed into a name to reckon with, innovating and constantly creating new products and know how for heating water.

Lochinvar is said to be one of the leading makers of highly efficient water-heaters, devoted in supplying various goods that aid in safe guarding the environment and propagating green practices through reprocessing work.
